About Me

|

Frontend developer Park Ju-cheol, still fighting today's errors.

1. I value both process and results.I proved this during the DIVE 2024 hackathon by building a polished service within 72 hours. From selecting Google Maps Platform to technical validation and implementation, I went through the process and achieved an award-winning result. I try to approach development with equal respect for process and outcome.

2. I try to write flexible, reusable code.In the Itzip project, I improved reusability and maintainability through composition-based shared component design and component-driven development with Storybook. This became a key foundation for consistent UI/UX in a 15-person team.

3. I value communication highly.I have actively collaborated with designers and backend developers across several projects. In Itzip, I helped build a communication system for a 15-person team and improved work efficiency. Since development is ultimately interaction between people, I consider communication a priority.

4. I enjoy the problem-solving process.In Posture Teacher, I improved performance by 5-10 times by switching from OpenCV to Mediapipe, and in Captain Donghae I worked through challenges in external API integration. Development challenges have always been learning opportunities for me.
